Battery and charger
Battery description
The MEGABRAS MPK-2000e micro-ohmmeter uses a sealed, rechargeable,
lead-acid, 12V - 7Ah battery. At the end of the useful life, that battery has to be
recycled or disposed of properly in order to take care of the environment.
Battery charger
The built-in battery charger is always active when the equipment is connected to
the mains supply, even if the ON/OFF# switch is turned off.
Charging procedure:
Check that the ON/OFF# key is OFF.
•

The indicator $ will keep on lightning with a red light up to completing the
•
charge. At that point, it will change to a green light, being like this up to the
equipment disconnection from the mains supply.
RS-232 output
The equipment has an RS-232) output in the control panel that can be used to
register measurements in a serial printer or data collector. The outputs are the
following ones:
Pin 2: Rx ; Pin 3: Tx ; Pin 5: Gnd;
Rate: 4800 bps
8 bits - no parity – 1 stop bit (8,n,1)
Note: In order to assure the compatibility with most printers available in the market, the
resistance units are shown with the following symbols:
uR = micro-ohm
mR = milli-ohm
R = ohm
